After being weaned, the deer usually enters the winter season after about 4 months. During the winter, the deer from the appearance-death look is relatively slow compared with the lactation period and the weaning period, but the requirements for feed and forage are higher, and the deer during the wintering period is more developed. The good and bad will have a great impact on the development of the deer in the spring of next year. 1 Developmental characteristics The young deer still have the characteristics of rapid growth and high plasticity during this period. The volume of rumen in Aberdeen is continuously expanding, the abdominal circumference is getting bigger, the development of internal organs is accelerated, weight gain is increased, appetite and digestive function are gradually increased, but from the appearance point of view, body height and body length are in a stage of slow growth. 2 Feeding Management 2.1 The male deer and puppies were reared in groups for 3 to 4 months after birth. The growth rate of the male deer significantly exceeded that of the pupal deer, and they also existed in terms of physiological changes and nutritional requirements. difference. The feed intakes of male deer and deer do not have the same amount. Therefore, most farms and farmers feed the deer separately, so that they can be treated differently to ensure the overall development level of the deer and avoid deer herds. Behind the deer. According to the different nutritional needs of male and female deer during feeding, different concentrates and raw materials should be given, and the feed must be evenly distributed so that each deer can eat enough feed. 2.2 Feeding and management of weak deer and young deer The young deer are mostly late-born deer with slower development due to illness or improper feeding methods. For them, we must promptly withdraw from large groups, prepare a warm shed separately, and carefully raise them by hand. Increasing feed nutrient and feeding times can have a certain effect on improving the survival rate of the deer and reducing the wintering mortality rate. 2.3 Strengthen the movement Due to the rumen plasticity of Aberdeen Deer, it is necessary to increase the amount of exercise to promote gastrointestinal motility, increase the frequency of defecation, increase appetite, and strengthen the constitution of the deer. Some farms mostly use the morning and afternoon movements for about 1 hour. If there are conditions, they can rush for one time at night. When the crickets start to pick up slowly, they rush to sizzle and let the deer familiar with the voice. 2.4 Demonstration of domesticated deer 2.4.1 Principles of domestication The use of deer's feeding habits, strong clustering and large plasticity, through repeated domestication of various environmental conditions, enables deer to establish conditioned reflexes and adapt to a complex environment. Conditions gradually remove timid, frightened, and uninhibited wildness, and develop in the direction that humanity needs. 2.4.2 Domestication points Adhere to a certain signal every day when eating, and develop the habit of listening to signals: When there is a domestication, there must be someone responsible for it. The signal must have certain rules, and it should not be changed arbitrarily: Pods, such as diced pieces or granules and small pieces of green radish can pick up food. The breeder can also lead the deer to familiarize themselves with the environment on the runway, so as to reduce the difficulties for the deer in the future, and to observe and diligently chase and make people defensive. 2.5 Strengthening management of winter deer house hygiene Due to the cold winter, the breeder should clean the feces of frozen ice around the house in time to avoid hurting the deer's legs. Feeding troughs should be regularly cleaned and sterilized to ensure cleanliness. Drinking water is required to be easily warmed, 2 times a day; Aberdeen deer housing should be filled with grass or dried dung for heating. The deer deer with a wetting bed should constantly change the bedding, while the keeper must strengthen it. Training work. 3 Feed supply According to the different characteristics of the development of Pita, the proportion of energy feed should be increased during the wintering period, and the feed should be rich in nutrients. A certain amount of minerals should be reasonably added according to the lack of minerals in different regions. The feed intake should be based on the amount of food intake in the next meal intake, generally the amount of winter concentrate 0.8 ~ 1.0kg/d. Reference feed formulation: 25% to 30% soybean meal, 60% to 65% corn, 8% bran, 2% to 3% bone meal, 1% salt, 1% Additive. To increase the growth rate and resistance to disease, a certain amount of auxin can be added. Roughage can be dried leaves, dried grass, grass powder, plus a certain amount of carrots a day, but not too much. Conditioned farms or farmers can either drink appropriate amount of soy milk or feed millet porridge to the deer, and try to make the deer's feed delicious, nutritious and diverse. 4 Summary During the wintering period, it is necessary to ensure the cleanliness of feeds and drinking water in the deer house and to ensure that there is no accumulated manure, no dirty water, and no snow accumulation. To ensure the quality of feed is easy to digest, it is forbidden to feed feeds with spoilage, high acidity, excessive moisture, and too much sandy soil to prevent the occurrence of metabolic diseases and digestive diseases. Keep the inside of the ring dry. Put the grass or dry dung in the shed to keep it warm and cold. Let the deer rest on their backs and ensure safe wintering.
